Fleets Analyzer - Aircraft Seat Quantities

Fleets Analyzer provides a range of seat quantity fields which are defined by cabin class for commercially-operated, passenger configured aircraft.  Cirium only researches seating and interior configuration data in Fleets Analyzer for large commercial jet and turboprop transports.  Definitions for these fields are provided below. Care should be taken when reconciling this data with airline schedule seating and ticket inventory per flight. 

The primary assignment of the seat class is made based on assessing the seat's intended design characteristics.  However many shorthaul aircraft are installed with the same economy seat design, pitch and width space dimensions throughout the complete cabin, whilst selling both a economy and business product onboard.  Airlines adapt this uniform configuration by allocating and selling a number of seats as a Business class product which will often include blocking the middle seat as a 'differentiator'.  Additionally, the quantity of business class seats allocated in this way can vary per route and schedule.

Number of Seats - total number of passenger seats installed on the aircraft
Economy Class Number of Seats - total number of economy product seats
Economy Class Seats Converted To Class - indicator if a quantity of the economy seats are sold as another cabin product or ticket class e.g "Business"
Economy Class Number of Convertible Seats - total indicative number of economy seats installed in a 'Converted To Class' configuration.  This will included middle seats which are blocked by a number of airline short-haul business products
Economy Class Number of Converted Seats - an indicative 'net' quantity of economy seats used in a convertible class configuration e.g Business.  This will exclude seats where the middle seat is blocked for sale and occupancy.

Please note: All seat data is representative of current fleet, therefore your cannot Trend seat (or internal fit) data. Seat OEM can change in an aircraft over time, so we're unable to trend it historically when it may have not been fitted at a given period end as the data only surfaces the current fit OEM.
